From the horses mouth (as it were)
1) There will be
NO GA allowed in on the day. Don't even bother phoning to ask as you'll just p

s off the Ops staff

(I tried to get a couple of people in and was refused - so not even any perks for the workers).
2)
Check the NOTAMS. There may be a TRA in force 10 mile radius butting up to the edge of the Bristol CTR Surface to FL40. This has yet to be confirmed but it's a possibility (we are pushing for it to be approved). Zlin is right - there will be a display but not by Concorde.
